Abstract

The interaction and electron injection processes of the LD14 dye on TiO2 cluster (anatase phase) in dye-sensitized solar cells (DSSCs) have been studied through calculations based on density functional theory (DFT) at the B3LYP, PBE and TPSS levels along with dispersion effects. The interaction of the LD14 dye with the TiO2 clusters was quantified using the DFT-D3 levels. The TDDFT calculations with the B3LYP-D3 in phase solvent (THF) in the LD14 and LD14-TiO2 models are the most suitable for describing the observed absorption energy bands. The free energy changes for electron injection support the better performance of LD14 on the TiO2 clusters.
